Abstract

The teaching mathematics in Indonesia has not achieved satisfying results. This can be seen from some survey findings of Indonesian students’ learning achievement in mathematics which show that students’ average scores in mathematics test were still low. The teaching process of mathematics in SMP N 6 Pekalongan faced some problems. When students solve mathematics problems which relate to their reasoning ability. One of the ways to solve the problems is the use of a learning model called video-aided Flipped Classroom. The objectives of the study are: (1) to find out the differences of students’ reasoning ability between those who learn through the Flipped classroom and those who learn through expository classroom; (2) to find out the reasoning ability of the students who learn in the video-aided Flipped Classroom. The data were collected through the use of reasoning ability test. T test and proportion test were used to analyse the data. The result shows that the reasoning ability of the students who learn in Flipped classroom is higher than the ability of those learning in expository classroom. Besides, the reasoning ability of those learned in the Flipped Classroom can achieve all of the learning targets.
